Abstract
The invention discloses a joint structure for conveniently fixing a catalytic converter. The joint structure comprises a sleeve and a connecting pipe, wherein the sleeve is in a flared shape, the small end of the sleeve is fixedly connected with the connecting pipe to form an exhaust passage, a fixing plate is sleeved on the connecting pipe, and the fixing plate is provided with at least two installation holes. With the adoption of the structure, the condition that the joint is loosened in the running process of a car is avoided, and the airtightness of an exhaust system is ensured.
Description
Technical field
The present invention relates to automobile technical field, specifically be convenient to the connecting head structure of fixed catalytic device.
Background technique
Catalyst converter is mounted in most important outer purifier in the automobile exhaust system, and the harmful gases such as CO, the HC that it can be discharged vehicle exhaust and NOx change harmless carbon dioxide, water and nitrogen into by oxidation and reduction.When the vehicle exhaust of high temperature passes through purification plant, purifying agent in the catalyst converter will strengthen the activity of CO, HC and three kinds of gases of NOx, impel it to carry out certain oxidation-reduction chemical reaction, wherein CO at high temperature is oxidized into colourless, nontoxic carbon dioxide; The HC compound at high temperature is oxidized to water (H20) and carbon dioxide; NOx is reduced into nitrogen and oxygen.Three kinds of harmful gases become innocuous gas, and vehicle exhaust is purified.
Catalyst converter is connected to the place, air outlet of gas exhaust manifold, and the very first time and waste gas react, and gas entered next link after reaction was finished, and just needs this moment a connecting head to be transitioned into next link.At present, general connecting head directly is connected with the next row device of air by pipeline, and whole connecting head does not adopt any fixing device, easily causes connecting head to occur loosening, affects the tightness of vent systems.
Summary of the invention
The invention provides the connecting head structure of being convenient to the fixed catalytic device, solved in the past that the connecting head of catalyst converter does not adopt any fixing device, easily cause connecting head to occur loosening, affect the bubble-tight problem of vent systems.
The present invention is that the technical solution problem is achieved through the following technical solutions: the connecting head structure of being convenient to the fixed catalytic device, comprise pullover and connecting tube, describedly pulloverly be horn-like, and a pullover less end is fixedly connected with and forms the exhaust passage with connecting tube, be socketed with fixed plate on the described connecting tube, described fixed plate is provided with at least two mounting holes.When using, pullover larger being used for is fixedly connected with catalyst converter, enters next link through the catalyst converter purified gas by connecting tube, and fixed plate is used for connecting tube is fixed, and then fixes whole connecting head.
Further, described connecting tube be shaped as cylindrical shape, and the nozzle diameter of connecting tube equates with the opening diameter of a pullover less end.
Further, the outer surface of described connecting tube is provided with outside thread, and fixed plate is provided with tapped through hole, and this through hole matches with connecting tube.Fix by screw thread between connecting tube and the fixed plate, be convenient to installation and removal.
Further, the opening diameter of a described pullover larger end is 2 ~ 3 times of opening diameter of a less end.
Further, the length of described connecting tube is 5 ~ 10cm.
Further, the length of described fixed plate is less than or equal to the opening diameter length of a pullover larger end.
The present invention compared with prior art has the following advantages and beneficial effect:
(1) the present invention fixes connecting tube by fixed plate by being fixed by socket plate at connecting tube, and then realizes the fixing of whole connecting head, has avoided automobile the loosening situation of connecting head to occur in running, thereby has guaranteed the tightness of vent systems.
(2) the present invention is simple in structure, easy operating, and practicability is stronger, also is convenient to simultaneously installation and removal.
